I was expecting to play games like assasins creed,Tomb raider legend,Race driver Grid,Lost planet etc...on high,but I was very disapointed when I saw that I couldn't get descend frame rate even with tomb raider legend somewhere I get 39fps...And lost planet I get 30fps I get huge loss of framerate with Asasin's Creed like from 50fps to 25fps in most areas...First I thought that it was my motherboard but I'm not sure.I would post my dxdiag report but I dont know were to download it.I'm not sure that laggyness is because of my Oc GPU,I get even worse on default clock,does someone have any idea why my games are all laggy?thanx in advance.( if someone has that dxdiag analysis software post it here so I can run it and post the detailed info about my PC)
